The real top five causes of major character death in mainstream superhero comics:
Marketing stunt where it's clear that the writers put a lot more effort into figuring out how they're going to bring them back once they've milked all the drama they can out of their death than they did into figuring out how to kill them off in the first place
Publisher convinced themselves that the best way to establish credentials for their latest villain-of-the-week was to have them randomly murder a popular character, having failed to learn from experience that this literally never works
Big-name writer decided to end their tenure on the character's title by breaking their toys on the way out, thus ensuring that they have the final word on the character's development, and in their hubris they believe they're influential enough that it will stick (hint: it won't)
New editor with nostalgic brain rot wanted to reset the status quo to how they remember it being when they were a kid, and the easiest way to do that was to kill off every character introduced more recently than 1987
